Abstract
A reclosable closure for a vial having a neck portion with a sealing flange surrounding an open end thereof is provided. The reclosable closure comprises a metal shell, having a top portion with an opening defined therethrough, and a depending side wall portion sized to engage the flange of the vial. A plastic top is provided having a top portion which overlies the top portion of the metal shell and surrounds the opening and which has an aperture defined therethrough aligned with the opening. The plastic top has an outer skirt which overlies the depending side wall portion of the metal shell, and an inner wall which depends from the top portion of the plastic top around the aperture. The inner wall has a first portion which extends through the opening, and a second portion which extends outwardly from the first portion to secure the plastic top to the metal shell. A reclosable cover is rotatably attached to the top by an integral hinge for rotation about a hinge axis. The cover is rotatable on the hinge between a first, closed position, where the cover overlies the top portion of the plastic top and the aperture, and a second, open position, in which the aperture is exposed.
